I prefer pounds per HP. We still don't know the Z/28's weight but it could be as low as 3,700. Also if we're talking RWHP the LS7 is as high as 480+ That's 7.7 lbs per RWHP. That's quite awesome.

Rear wheel on the ls7 vettes is always 460 give or take a couple. That's with a shorter drivetrain and special rear transaxle. The Z28 will have less rwhp because of more shtuff to spin under there plus a longer (little heavier) driveshaft. And, it will be toting around several hundred lbs. I hope it isn't something dismal like 425 rear wheel - have a feeling that's what will be seen.
